In this Love & Hip Hop Atlanta highlight clip, Lovely Mimi hits the club with her boss Sierra and co-worker Moriah in hopes that getting to know Sierra on a personal level will help tone down their office beef.

Well, it didn’t. Sierra was all negative vibes in the club, and Mimi wasn’t having any of it. She spent a good minute listening to Sierra trash talk her, but went from 0 to 100 (decibels) real quick once she could get a word in.

After Mimi quits “the mother f–king glam shop,” Sierra claims she “wants to be black so f–king bad.” Those are apparently fighting words for Mimi, because she hops off that couch to scrap without missing a beat.
